Applicationlled December 30, 1918. Serial No. 268,890.

To all wlw/1a 'it may concern Be it known that I, @Hannes E. TAYLOR, a citizen of the United States, and a resident of Sealy, county of Austin, and State of Texas, have invented certain new and useful improvements in Cotton-Picking llozzles, of which the following is a specification.

My present invention relates generally to cotton picking apparatus and more particularly to a cotton picking nozzle for a vacuum or suction apparatus, my object being the provision of a nozzle by means of which the effective action of the suction may be readily controlled with a suction line of constant pressure.

A further object of my invention is the provision of a simple, inexpensive nozzle capable of use with various types of suction lines, which may be easily handled, and quickly adjusted to vary the effective pressure at its mouth in use.

1n the accompanying drawing illustrate ing my improved nozzle, and forming a part of this specification:

Figure 1 is a side view of the nozzle comw plete;

Fig. 2 is a vertical longitudinal section taken partially therethrough on the line 2-2 of Fig. l;

Fig. 3 is a transverse section taken substantially on line 3-3, Fig. 1.

Referring now to these figures, my inlproved nozzle consists of a pair of telescoping relatively adjustable tubes 10 and 11, the former of which surmounts the forward portion of the latter, whose rear end is free to receive the end of a flexible suction or vacuum line in which, as is usual, the pressure is constant, or practically so.

Intermediate its ends, the inner tube 11 has a peripherally proj ecting stud l2 which is adjustable by movement of the outer tn be 10 within a series of slots of the latter adj acent its rear end. These slots include a longitudinal slot 13 from whichat separate points in the length thereof project a series of short transverse slots 14, 15, 16 andl' so that by the simple expedient of shifting tube 10 by rotation and longitudinal move- .nient thereof to change the position of the stud 12 from one of the transverse slots to another, the outer tube 10 may be secured in desired longitudinal adjustment with respect to the tube 11 for the purpose which will be now described.

iidjacentits forward end and thus contiguous to the intake aperture 1S of its intake end 19, the wall of the outer tube 10 has a number of annular series of small apertures 2O more or less covered by the front inner end of the tube 11, dependent upon longitudinal adjustment of tube 1() on the tube 11,

Thus with the parts in what may be said to be the normal position, with the stud 12 in the forward slot 111, the forward end of the inner tube 11 extends into engagement with the intake end 19 of the tube 10 around its intake opening 18 through which the cotton is sucked, and it is obvious that when the parts are so positioned in relation to one another the full effect of the suction' within the suction line is had through the intake opening 1S.

When it is desired, however, to reduce the effect of the suction upon the cotton in the course of picking, the outer tube l0 is shifted longitudinally and forwardly with respect to the tube 11 so as to expose more or less of the series of apertures 2O and in this way draw air inwardly through such openings 2O as are exposed so as to cor respondingly decrease the effect of the suction through the intake opening 18.

By the means previously described consist ing of the stud 12 and bayonet slots of the tube 10, the latter may be secured in various positions yof adjustment so that an adjustw nient when once made,` may be maintained if desired, without requiring the attention of the operator, until further adjustment is deemed necessary.

For the purpose of adjusting the outer tube 10, it may have an annular ring or rib 21 around its rear end and it is obvious that my invention thus provides simple, inexpensive means which may be readily inanipulated and adjusted and which will be effective and efficient in its action for the purposes stated.

I claim:

1. A cotton picking nozzle of the character described consisting of a pair of telescoping adjustable tubes, one of said tubes having an intake mouth at one end and openings in its wall for a portion of its length normally covered by the other tube, said apertured tube having a series of baycnet slots and the other tube having a stud movable in the said bayonet slots for the purpose described.

2. Acotton picking nozzle of the eharacter described comprising a pair of tubes one of which has anV outstanding stud at a point intermediate its ends, the other tube telescoping said first named tube and having a longitudinal slot adjacent one end and a plurality of transverse slots communicating with the longitudinal slot to receive the stud of the first tube, said last 10 named tube having an intake opening at its opposite end forming a cotton receiving mouth and having annular series of apertures for a portion of its length and extending froin 1ts last named end, all for the purpose described.
